Description:
Another one.

Thanks to almostmatt1 and rockygaming4725 for pointing out the off axis/diagonal wall here. Spent quite a bit of time trying to get it to work, but once I understood what I had to do it didn't take too long.

Could have used a rocket by the exit to get past the door extending out into the void quicker if I had saved one and had conserved enough health. Also several other things that could have been a bit faster, but the IL non-TAS record is 0:59, or 0:30 in the 9:42 D2All TAS, so it's much faster. With a plasma rifle at the start from a D2All you could save even more time.

The reason you can go through the wall here is because a wall is slightly tilted away from the x-axis, but because the angle off the corner is just barely larger than 90 degrees it means I need quite a bit of momentum in both directions to get it to work, hence the double rocket boost, though it might be possible with only 1. So together with some very precise position on the frame before I go through the wall and high momentum I get the extra speed needed (because of slide movement against the wall) to go above the max speed limit of 30 units per tic for 1 frame and go through the wall. Doomguy is 32x32 units so at least 32 unit per tic is needed. Technical description can be found here under the void glide section: www.doomworld.com/forum/topic/87199-the-doom-movem…

Finding a way to do it non-TAS might be impossible, even if it is possible it would probably take too long to set up to save time, but who knows.

Tools used: frame by frame building.

    Plot twist: He says it's TAS but it's just him casually playing.
  • @johnkimble2258
    It's insane that time saves / skips like these are still being found nearly 30 years after DOOM II came out.
  • @TewgyTaylor
    As usual I don't even entirely know what happened. Amazing work from the legend himself!
  • @nida4602
    This is insane. Imagine if one day this can be used in a non-TAS run... Great job as always, man!
  • @poab3036
    Crazy the progression of void glides

    Dude. Thank you so much for the work you put into this classic game! I’ve come to enjoy your run notes as much as your runs. I’ve been combing through all your old video just to read your notes!

    best way to describe this run is: "Execuse me, what?"

    I can't wait to see you in "Prodeus 2" You and your next speedrun, I bet it would be under 3h or less than that. And I also hope that you will get your hands on the game, same as last time early access!

    Damn it ZM... you're going to force Matt to make a new d2all TAS now... poor guy.
